IIS6 will not serve a 404 error for .asp

[USCountytrader]

Hello,
currently on a win2003 server using IIS6. My problem is with the
classic asp pages. All my asp pages are serving up fine. But due to a recent restructure of the website, all the url's changed. I recently discovered that all my non existing .asp url's are returning 500 errors instead of 404. It's really weird! I can make up any page name I want, but if it ends with .asp it returns a 500 error instead of 404. This is only happening with .asp urls, any other page extension returns the correct header status. Any one have any ideas?

Are you using relative, virtual, or absolute hyperlinks in the 404.asp page?

Can you turn off Friendly Error messages to see what the error might be?

Parent paths are enabled on the server.

Friendly URL's is turned off, yet it shows nothing but:
HTTP/1.1 500 Server Error

Web Log shows:
/test.asp ¦-¦ASP_0147¦500_Server_Error 80

Can get a 404 page for .htm, .html etc, Just not .asp

I am guessing that the ASP.DLL is the one processing the .asp page headers, not the others. Where do you specify where ASP.DLL sends a 404?

BTW, I cannot find a 404.asp page

Also, even non existing .aspx and .jsp pages serve the correct 404 response. Kindda weird that .aspx will, but not .asp

Do you have a custom 404 error handler installed in IIS?
